Source for Copper Narrow Stripping for Embossed Plant Markers?

I'm posting this in both this forum and Hands on Home, if that's okay.

I'm trying to find a roll of narrow copper stripping (like copper tape, only without adhesive on one side) to use for making my own embossed plant markers. I need something about 1-1.5" wide and thin enough to easily nip with tin snips and form around the wire I'll use for the stakes.

The people at Lowe's looked at me like I had two heads, and my aisle-by-aisle search turned up nothing. Wal-Mart didn't have any, either. Anyone have any good, inexpensive sources?

Would galvinized aluminum stripping work just as well for plant markers? I thought the copper would be pretty as it aged, but if it's really expensive, maybe another metal would work better? Thanks!
